ABSTRACT:
The technique of measuring the duty cycle of a digital signal of known repetition rate is disclosed. It makes use of the fact that the probability of the digital signal being at the high level is related to its duty cycle when the signal is sampled at a frequency incoherent with the repetition rate. The apparatus in one embodiment includes a random sampler for sampling the digital signal under measurement, and digital counters which count the total number of samples and the number of samples whose values are at one of the two digital levels.
